摘　　要：讨论了一种高速(3MSPS)、12位分辨率的数据采集卡的设计要点,其中包括通道转换、高速A/D转换、数据缓存、中断扩展、计算机接口等电路的设计。该采集卡可直接插入计算机的扩展槽,构成一存贮量大、兼容性好、性价比高的数据采集系统。The main points of the design of a high speed (3MSPS) and high resolution(12 bit) data acquisition board, including the multi channel converter, high speed ADC (AD 1672), data buffer memory, interruption expansion and computer interface, are described in this paper. It can be inserted to the expansion slot of a computer forming a compatible data acquisition system with a large buffer memory and a high ratio of function to cost.
